Sometimes the answer to your problems is right in front of you. But somehow you just can’t grasp it until you’ve had a bit of an enlightenment experience. This happened to me a couple of weeks ago.
You never touched Groovy, nor did you jump on the Scala train. Clojure never attracted you; and you heard about Ceylon long after the language had already died. You are one of those old-fashioned Java folks! But now, after all those years, you want to join the cool Kotlin kids. So, where to start? Let’s discover the language together by decompiling it to Java code. Today: The things we tend to forget!
Dear Diary,
"Hobbits really are amazing creatures. You can learn all that there is to know about their ways in a month, and yet after a hundred years they can still surprise you"[1]. The astonishment Gandalf experiences, that you know something very well but somehow overlooked it, is not unfamiliar to me. Well, let me tell you a story…
Dear Emily,
You know that feeling when it suddenly clicks? Something you never knew or could not understand. And then, boom, this new knowledge is there for the taking. Well, I had this experience some time ago.

You’ll do some largemouth fishing another time
You just got too much on your plate to bait and cast a line
You can always put a rain check in his hand
'Til you can’t
